CRANK LOCK FORLBOX CARS.

i Application filed July 25, 1925.

To all whom it may 00mm.-

Be it known that we, AnoLrH E. ASHLE- MAN and THOMAS E. HANEY, citizensof the United States, residing at \Vaco, in the county of McLennan andState of Texas, have invented a new and useful Crank Lock for Box Cars,of which the following is a specification.

The present invention has reference to a combined closure operator andlock, the primary object of the invention being to provide a device ofthis character especially designed for use in connection with slidingclosures, of rolling stock the operating device being such as to lockthe closure in its open or closed position.

Another object of the invention is the provision of means for moving theclosure-to its open or closed position, with the minimum amount ofexertion on the part of the operator.

With the foregoing and other objects in view which will appear as thedescription proceeds the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, may be made within thescope of what is claimed, without departing from the spirit of theinvention.

Referring to the drawing:

Figure 1 is an elevational view illustrating a sliding closure suppliedwith an operating device constructed in accordance with the invention.

Figure 2 is a sectional view taken on line 22 of Figure 1.

Referring to the drawing in detail, the reference character 5 indicatesthe body portion of a box car which is of the usual construction andprovided with the usual door openings.

Secured along the upper edge of each door opening is a flanged member 6pro vided with a depending flange 7 forming a guide for the rollers 8carried at the upper edge of the closure 9.

Extending along the lower edge of each door opening, is a track 10 onwhich the rollers 1.1 operate, the rollers 11 being supported betweenthe plate 12 and closure 9 as clearly shown by Figure 2 of the draw-Fositioned under the trackway 10 is a rack bar 13 that is engaged by thepinion Serial No. 46,057.

1% supported by the bracket 15 that is secured to the lower edge of theclosure. An operating handle indicated at 16 is provided with a shaft 17that extends through the pinion 141 and has connection therewith in sucha way that movement of the operating handle will produce a relativemovement of the pinion to move the closure along the track 10.

The bracket 15 extends upwardly terminating at an appreciable distanceabove the lower edge of the closure 9 where the same is bolted to theclosure as at 18. EX- tending laterally from the upper portion of thebracket 15 is a keeper 19 provided with an opening 20 through which asuitable seal or lock may be passed, for locking the closure after ithas been moved to the desired position.

Pivotally connected with the operating handle 16 is a locking member 21provided with an opening to accommodate the keeper 19 to the end thatwhen the locking member 21 is positioned as shown by Figure 2, and asuitable lock is placed through the opening in the keeper, movement ofthe operating handle as well as the pinion connected therewith, will beprevented, there by locking the closure against movement.

In the operation of the device, the locking member 21 is moved from aposition as shown in Figure 2, to a position as shown in dotted lines inFigure 2 and the handle 16 operated to rotate the pinion 141. It willthus be seenthat the rotation of the pinion will cause the slidingclosure 9 to move longitudinally of the track 10, to the desiredposition, whereupon the locking member 21 is moved to its activeposition, thereby eliminating any possibility of moving the door. 7

From the foregoing it will be obvious that due to this construction, theclosure may be locked either in its closed or semiclosed positions, andthereby adapt the closure and car equipped with the device, for varioususages.

lVe claim:

A sliding door for cars including a body portion, a plate secured to thelower end of the door and having a downwardly extended portion, the mainportion of the plate being disposed in spaced relation with the lowerend of the body portion, rollers positioned between-the door and plate,a track secured to the car and having a depending flange formed alongone edge thereof, a rack bar secured on the inner surface of the track,a bracket member secured to the door and overlying the plate, saidbracket member having an inwardly and upwardly extended portion, apinion supported by the bracket member and adapted to mesh with the rackbar to operate the door a shaft on which the pinion is mounted, anoperating handle secured to 10 the shaft for rotating the pinion, andmeans for locking the operating handle against movement,

In testimony that we claim the foregoing as our own, we have heretoaflixed our sig- 15 natures.

ADOLPH E. ASHLEMAN. THOMAS E. HANEY.
